  • Publication number: 20200119753
    Abstract: A device includes a data path, a first interface connected to the data path and configured to receive a request from a processor package to write a data value to a memory address, and a controller connected to the data path and configured to receive the request to write the data value to the memory address and to calculate a Hamming code of the data value. The controller is configured to transmit the data value and the Hamming code on the data path. The device includes an external memory interleave connected to the data path. The external memory interleave is configured to receive the data value and calculate a test Hamming code of the data value and to determine whether to send the data value to an external memory interface to be written to the memory address based on a comparison of the Hamming code and the test Hamming code.

  • Publication number: 20200117619
    Abstract: A device includes a data path, a first interface configured to receive a first memory access request from a first peripheral device, and a second interface configured to receive a second memory access request from a second peripheral device. The device further includes an arbiter circuit configured to determine a first destination device connected to the data path and associated with the first memory access request and a first credit threshold corresponding to the first memory access request. The arbiter circuit is further configured to determine a second destination device connected to the data path and associated with the second memory access request and a second credit threshold corresponding to the second memory access request. The arbiter circuit is configured to arbitrate access to the data path by the first memory access request and the second memory access request based on the first credit threshold and the second credit threshold.

  • Publication number: 20200117618
    Abstract: A device includes a data path, a first interface configured to receive a first memory access request from a first peripheral device, and a second interface configured to receive a second memory access request from a second peripheral device. The device further includes an arbiter circuit configured to, in a first clock cycle, a pre-arbitration winner between a first memory access request and a second memory access request based on a first number of credits allocated to a first destination device and a second number of credits allocated to a second destination device. The arbiter circuit is further configured to, in a second clock cycle select a final arbitration winner from among the pre-arbitration winner and a subsequent memory access request based on a comparison of a priority of the pre-arbitration winner and a priority of the subsequent memory access request.

  • Patent number: 9588148
    Abstract: A transformer for monitoring current in a power cable is magnetically linked with the power cable connected to the electrical device, where the transformer produces a changing transformer signal in response to the presence of a changing current within the power cable. An input circuit located proximate to the transformer and having an output terminal and being electrically connected to the transformer so as to receive the changing transformer signal. The input circuit produces, in response to receiving the changing transformer signal, one of a first signal representative of the changing current, and a first circuit condition at the output terminal of the input circuit representative of the changing current in the power cable. The input circuit includes an impedance set having an effective impedance that comprises a plurality of elements, wherein at least one of the elements is not electrically connected to the remaining the plurality of elements.
